I just spent the day watching a local drift event. I rode my bike there and it was awesome. For the nerds: my two favorite cars there were a 3SGE-swapped TE72 Corolla and an S14 with a RB dry sump setup.
Commuting? general transportation? Cars are completely unnecessary. For motorsports, however, cars ARE necessary. What are you gonna do, drift a bike?
A glimpse into the brain of a car enthusiast that hates cars.
Cars are fine for specialty uses. Like giving handicapped people who can't use busses and trains a car is fine. Giving emergency responders cars is fine. Cars for entertainment, cultural and hobby uses are also fine as the emissions they make is negligible. Cars might also have legitimate commercial and industrial uses, like inspection vehicles. A limited taxi service might also be a good idea, especially for the disabled or elderly.
But for personal transportation? No, absolutely not. Cities should be planned so living within biking or walking distance of your workplace becomes the norm. This should be supplemented with good non-polluting public transit systems capable of quickly and efficiently handling local, regional as well as international travel.
Cars are inevitable but they shouldn't be everywhere, you right.
